Influence of micro climatic variables on population dynamics of Thrips tabaci Lindeman on onion
Onion thrips are of major concern in onion production. Thrips populations are influenced by various climatic variables, different transplanting dates, and spacings. Considering this, an investigation was undertaken to find out the influence of climatic variables on Thrips tabaci Lindeman under three different planting dates in West Bengal, India (15th Aug, 30th Aug, 14th Sept during kharif season and 30th Nov, 15th Dec and 30th Dec during rabi season) and three different spacings viz., 15cm × 10cm,15cm × 15cm and 20cm ×15cm(plant to plant by row to row)for two consecutive years. Thrips populations were not observed on Kharif planted onion which might be due to frequent rainfall which acts as a controlling factor of thrips. Closer spacing with dense foliage supported more built-up of thrips population than the widely spaced crop with sparse vegetation. Out of three dates of planting of rabi season crop, the 30th November planted onion crop was comparatively less infested by T. tabaci. The study unveiled that 30th November would be the best time to transplant the rabi onion crop with a spacing of 15cm × 10cm in the Gangetic plains of West Bengal for better yield. Also, the ambient temperature and canopy temperature were found to have a significant positive correlation while canopy humidity was negatively correlated with the thrips population. Besides the mentioned microclimatic variables, incidental and reflected photosynthetically active radiation also revealed a correlation with thrips population fluctuations on a few occasions.
Designing of Moringa incorporated instant food product
Standardization of nutritious and organoleptically suitable food products with market available foods is a challenge for food scientists and entrepreneurs. However, the benefits of such food-based strategies to prevent micronutrient malnutrition are manifold. Indian diets provide mostly non-heme iron, which is very poorly absorbed (only 2-20% bioavailability). Women in developing countries often consume inadequate amounts of micronutrients because of their limited intake of animal products, fruits, vegetables, and fortified foods. Intakes of micronutrients less than the recommended values increase a woman’s risk of having micronutrient deficiencies. The adverse effects of deficiencies in vitamin A, iron, and folic acid, including night-blindness in pregnant and lactating women and iron-deficiency anemia, are well known. Low intakes of nutrients including zinc, calcium, riboflavin, vitamin B6, and vitamin B12, also have consequences for women’s health, pregnancy outcome, and the health and nutritional status of breastfed children. Multiple deficiencies coexist, so the benefit of multiple micronutrient supplements is becoming increasingly apparent. These issues need to be discussed and guidance be provided on the selection of appropriate food for women of reproductive age in developing countries. In the study, Optimization of process parameters via RSM Box-Behnken design was done and based on the same product was finalised. The results of the present study indicated that inspite of nutrient losses, there is enough β-carotene retained in the developed instant dip drink food product to help in the eradication of several micronutrient deficiencies. It is need of the hour to promote moringa incorporation into the diet in India for a long way towards not only in alleviating micronutrient deficiencies, but also towards the development of functional foods for various chronic degenerative disorders. These efforts could also be an additional source of income generation, employment and export opportunities.
Field Efficacy of Biorational Insecticides Based Modules for the Management of Helicoverpa armigera (Hübner) in Chickpea
Experiments were conducted at Banda University of Agricultural & Technology, Banda in 2018-19 and 2019-2020 to evaluate the field efficacy of biorational insecticides-based modules consisting Azadirachtin, NSKE, Bt, NSKE and Indoxacarb against Helicoverpa armigera in chickpea. The Indoxacarb 15.8 EC @ 50 g a.i./ha + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha was found most effective and in reducing H. armigera population. The field treated with this module recorded least pod damage 1.68% and 1.27% during 2018-19 and 2019-20, respectively. Data revealed that the fields treated with Indoxacarb 15.8 EC @ 50 g a.i./ha + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha recorded highest yield of 21.3 q/ha & 22.82 q/ha during both the year and found to be the best treatment. The maximum cost benefit (C: B) ratio of 1: 5.33 and 1: 8.17 was obtained from Indoxacarb 15.8 EC + Chlorantraniliprole 18.5 SC @ 30 g a.i./ha during 2018-19 & 2019-20, respectively.
Effect of irrigation schedules and nutrient management practices on growth, yield and economics of transplanted autumn rice
The present investigation was carried out during autumn season of 2017 and 2018 at ICR Farm, Assam Agricultural University, Jorhat to see how varied irrigation schedules and nutrient management practices affect the performance of transplanted autumn rice. Results showed that different irrigation schedules significantly effect growth and yield of transplanted autumn rice. Application of 5 cm irrigation at 3 days after disappearance of ponded water (DADPW) resulted in higher plant height, shoot dry weight and root volume at different phenological stages. The highest plant height, shoot dry weight and root volume at different phenological stages were recorded by recommended doses of fertilizer (RDF) which was at par with integrated nutrient management (INM) treatment. With 5 cm irrigation at 3 DADPW, the mean maximum yield contributing characters and grain yield and straw yield were recorded. Application of RDF provided highest yield attributing characters and grain yield and straw yield which was statistically at par with INM. Among all the treatment combinations, 5 cm irrigation at 3 DADPW with the application of INM (I2F3) recorded the highest gross return, net return and B:C ratio followed by 5 cm irrigation at 3 DADPW with the application of RDF (I2F4).
Genotype ×environment interaction on yield of maize single cross hybrids developed from tropical inbred lines of CIMMTY using AMMI
In this research, we evaluated at how the interactions between genotype and environment (GEI) affected the grain yield of 41 different maize hybrids in 2020 on three test locations (E1, E2, and E3). When we pooled all of the sources of variance analysis, we found substantial differences. The studies revealed that G14, G7, G22, G3, G35, G9, G32, G38, G24, G23, and G26 were the best stable genotypes. G14 emerges as the most acceptable and favorable genotype of them. Locations that were labile were E2 > E3 > E1. The least G×E interaction was seen in G30, G19, G4, G18, G34, G15, G13, G21, G6, G37, and G36, which also had the most unstable hybrids and the lowest grain yield overall. The recommended hybrids for each region include G7, G10, G11, G14, G20, G22, G23, G27, G32, G38, G41, and G40 had particular stability in E1. The hybrids G2, G4, G8, G21, G28, G29, and G33 displayed particular stability in the E2 location. In the E3 experimental area, the hybrids G3, G5, G8, G12, G17, G16, G18, G26, G30, G35, and G36 had a specific level of stability. G24 >G38 >G9 >G32 > G12 >G41 >G7 >G28 >G14 and G3 were superior genotypes for grain yield and GEI impact, and can be suggested for further research based on the AMMI stability value (ASV) and genotype selection index (GSI).
